    Main Results:

    • Dose-response curves aid in selecting equitoxic doses and estimating relative safety and toxic potency.
    • Enzyme inducers can reveal the involvement of metabolic transformations, but their specific selection is critical.
    • Interactions and environmental factors, such as pathology and body temperature, significantly impact toxic responses.

    Conclusions:

    • Standardized toxicity testing necessitates careful consideration of test procedures, dose-response relationships, and the role of metabolic activation.
    • Understanding the influence of enzyme inducers and external factors is vital for accurate toxicological evaluations.
    • Further research into these variables will improve the reliability and reproducibility of toxicity studies.
